Do I need a power conditioner?


I’m in the process of dropping a dedicated 20 amp circuit or 2 into the music room.
So if I have a dedicated circuit for the amp, and a dedicated circuit for everything else,
is a conditioner useful?
I have several fairly decent systems going that I tweek and retweek.
Just got around to upgrading cables. Avoided conditioners because, in general, they dampen the presentation.
Was using a PS Audio PPP for low power components. But fell for the Shunyata spiel.
Plugged in a Hydra 4 with a Python Helix and was very happy with how it cleaned up the Zu Druids.
Seems high sensitivity speakers maybe reveal the grunge also.
Moved it to my system with the Martin Logans and the presentation seemed a bit lean and just a bit lifeless, using just copperhead cable to Hydra. (using all Pangea to get from the Hydra to other components.)
Then I put a Black Mamba from Classe amp straight to the wall and Wow! Single most significant tweek ever for me.
So I’m thinking, maybe I don’t need the Denali I ordered if I just use a couple dedicated circuits and some Shunyata power cords everywhere.
Opinions?
Thanks. :)

Thanks @lak @knghifi for your responses. Are you guys referring to the MC-6 or the MC-6 Hemisphere? The hemisphere has Furutech GTX-D (R) receptacles but unsure about the IEC. Not sure how much better the NCFs would be. That would indeed be an interesting experiment. 

Excuse my ignorance but how would you go about adding a grounding post on the MC-6?

That HB Cable Marble looks like a beast. Might be able to audition a Powerstar Horizon and do a direct comparison to the MC-6 Hem. Looks like the primary difference is the # of outlets? 9lbs vs 40 lbs whew.
@bacon333, I have the MC-6. I was told that the MC-6 Hemisphere is superior to the MC-6 and works on different principals.
I want to correct the above statement I made about how the MC-6 Hemisphere works. The MC-6 Hemisphere does work on the same principal as the MC-6 however, the parts are upgraded and there is an advanced waveguide system along with a ceramic-tempered, hard, anodized aluminum receptacle mounting and bottom plates for vibration-resistant mounting systems on the internal waveguides and receptacles.  

Hullo:
I have a BPT2.5 balanced unit that I got used here on Audiogon.  It came without any instructions at least to me.  A question for anyone who can help.  Is it safe to use it to power Synergistic MPCs and FEQs which have two pronged plugs but have separate 3 prong plugs solely for grounding that must go into a separate socked altogether?

Thanks for any help.  Perhaps I should contact Synergistic?
